Abstract

The size frequency distribution and reproductive biology of Chaiybdis (Chatybdis) forktus (Linnaeus) were
studied from the trawl fishery of Cochin during January-March, 1989. The fishery was mainly supported
by adult crab in the size range 60-154 mm for male and 65-120 mm for female. Overall size frequency
distribution showed a unimodal pattern in both sexes, the bulk of the fishery being contributed by the
size groups 80-109 mm C. W. Males formed about two third of the population. The minimum size of
ovigerous female measured 66 mm C. W. Fecundity ranged from 52,350 to 3,09,250, the rate of egg
production being directly proportional to the size. Active breeding of the spedes was noticed throughout
the period.
